i am trying to enable sensor processing engine gpio in Agx xavier .but unable to find tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg file in kernel source code and
pinmux.0x0c2f1800 = 0x00000003; # CONFIG BB0 output
pinmux.0x0c303040 = 0x0000c004; # can1_stb_pbb0
pinmux.0x0c303048 = 0x0000c044; # can1_en_pbb1
unable to find addresses in source code .
can anyone helpme how to find that and enable pinmux for SPE.
That file (tegra19x-mb1-pinmux-p2888-0000-a04-p2822-0000-b01.cfg) is not in kernel source package. It’s in BSP package.
For example, 32.5:
L4T Driver Package (BSP)
hi i found the file but after configuring path variable ,unable to build the the firmware .
t23x target_specific.mk error is coming.
I’m not sure about your comment by ‘unable to build the the firmware.’
That file need not re-build. Just update the file and re-flash the device. New config should take effect.
spe.bin we need to update right for GPIO enabling that i mentione as firmware
Can you share the detailed information when you met the issue?
- BSP version
- Failure logs.
- Target platform.
i took 35.1 jetson platform for AGX xavier internal EMMC.
now able to flash the GPIO app changes in AGX xavier ,but GPIO IRQ triggered print is not coming.
please let me know any further details reuqired.
Have you ever followed the instructions in “rt-aux-cpu-demo-fsp/doc/gpio.md”?
There are several configurations to be updated.
And also, you can check the GPIO pin level. For example, when SPE firmware’s running, check whether the GPIO OUT toggles.
